At a temperature of 309k and a pressure of 0.7 MPa, the density of reptile is 12 kg per square meter. What is the molar mass of the gas?
Task data: T (temperature) = 309 K; P (pressure) = 0.7 MPa (0.7 * 10 ^ 6 Pa); ρ (density of the taken gas) = 12 kg / m3.
Constants: R (universal gas constant) = 8.31 J / (mol * K).
To calculate the molar mass of the taken gas, we will use the Mendeleev-Clapeyron law: P * V = m / M * R * T and M = m * R * T / (P * V) = ρ * R * T / P.
Calculation: M = 12 * 8.31 * 309 / (0.7 * 10 ^ 6) = 0.044 kg / mol.
Answer: The molar mass of the gas taken is 0.044 kg / mol.
